Lucas Fernandes Mariano (born 24 September 1993) is a Brazilian basketball player who plays for Franca of the NBB.

Encouraged by his mother, a former professional athlete with passages through Brasília, Ponta Grossa and Franca, Lucas began his career in basketball at Escola Lance Livre, aged just seven.

The situation changed in the 2012–13 season, when Lula Ferreira replaced Hélio Rubens in charge of the Franca team.

Three months later, he played in his first final for Mogi, being defeated by São José and taking the vice-championship in Campeonato Paulista.

After leaving Mogi das Cruzes, Mariano played for Lobos Brasília and he was considered at the time one of the best centers in the league.
